The present machine is adapted to be driven along a carpet through themedium Fig. 12' is an enlarged.

of the electric motor 1 journaled in the frame Q 2 supported on thebracket 3secured to the lower part of the machine frame 4 by means ofthe screws 5. Locating the motor below the sewing mechanism will serveas a counterbalance for the machine, whichwo-uldotherwise betop heavyand awkward to manage- To assist this counterbalancing feature and tokeep the device from lateral movement, the trolley 6, carried by thebracket 3, is guided on the rod 7 supported on the arms 8 and 9projecting from the standards 10 and 11, which standards are adapted torest on the floor.

The rack l2 is secured to the upper ends of the standards by the screwsl314'and the entire machine, including the sewing mechanism and motor,will be supported by means of the trolley rolls l5 carriedby the trolleyframe 16.. This frame, Fig. '7, is secured tothe machine frame by thescrew 17, and it carrles part of the mechanism for actuating the machinealong the rack, comprising the rack pinion'l8 (see also Fig. 3)'journaled on the rod 19 secured .in the said trolley frame. The arm 20is also journaled on said rod and-itcarries the pawl 21 adapted to,

engage the ratchetfwheel 22 secured to the rack pmion 1 8. The feed isactuated from the eccentric 23 on the drive shaft 24, which shaft isdriven from the motor through the medium of the belt 25, Figs. 1 and 2,and.

pulley 26.

screw 28.

The eccentric strap arm 27 is. pivotally connected to the arm 20 by. the

The main shaft 29 is driven from the.

shaft2 by the pinion 30 meshing. with the large gear 31 journaled. onthe short rod 32 secured in the machine frame 4 as shown more clearly inFig. 8, and the pinion 33 on said main shaft also meshing with saidlarge gear.

The needle 34 is secured to the slide 35 operatively mounted in thebracket 36 secured to the machine frame by the screws 37. This slide isreciprocated through the medium of the bevel gear 38, secured to thelarge spur gear 31, meshing with the bevel pinion 39 journaled on thepin 40 located in. the end of the arm 41 integral with the machineframe. The plate 42 is secured to this bevel pinion and it carries theroll 43 adapted to operate in the cam groove 44 of the lever 45pivotally mounted on the screw 46 of the machine frame. The free end ofthis lever has the elongated slot 47 embracing the pin 48 of the slide35. 49 is the tension disk carried by said lever over which the thread50 runs and is intermediate of the delivery spool 51 and the needle.

The shuttle 52 is actuated in the race 53 through the medium of wellknown mechanism comprising the lever 54, journaled on the screw 55secured to the machine frame. This lever has the usual arms 56, 57 tocarry the shuttle in its reciprocating movements. This lever isoscillated in the usual manner from a cam (not shown). Mechanism forchanging from a lock stitch to a loop stitch is shown more clearlyin'Figs. 1 and 9.

58 is a housing plate secured to the main shaft 29 and it has theinwardly projecting hub 59 on which hub is journaled the cam plate 60having the cam groove 61. The looper 62, Figs. 2 and 9, projects fromthe lower end of the arm 62 and in conjunction with the needle forms thewell known loop. This arm is removably secured to the arm 63 by screws64, and the upper end of this latter arm is pivotally supported on thesame screw 55 as the shuttle carrying arm 54. 65 is a roll carried bysaid arm adapted to enter the cam groove 61. The change from a lock to aloop stitch is effected through the medium of the change pin 66 shown indetail in Fig. 10. This pin operates in hole 67 of the plate 58, and isprovided with the circumferential grooves 68 and 69 adapted to receivethe vertically operated locking pin 7 0. As shown in Fig.

9, the change pin is withdrawn from contact with the cam and said camwill remain idle while the shuttle is in operation. The end of thelocking pin 70 will then be in the groove 69. When the looper is to beoperated, the shuttle is removed and the change pin is slightly turnedto bring the lower end of the locking pin in line with the longitudinalgroove 71, Fig. 10. When the inner end of said change pin is pushed intothe hole 71 of the cam, the locking pin'will lie in the circumferentialgroove-68 and the looper will operate. When the looper is in operation,both spools, 51, 51 are used.

72 is the carpet support, which can be of any desired length toaccommodate carpets of various sizes. This support is removably locatedin the upper forked ends 73, 74 of the brackets or supporting guides 75,76.

One of said forked ends, 74-, is shown more ings of the carpet supporterbrackets. The

lower threaded end of these screws carry the jam nuts 84. Surroundingthese screws and restingon the base of the forked ends of brackets 75,76 are the springs 86, which springs project into holes in the bottom ofthe wooden carpet supporter 72.

87 are plates located on each side of the carpet supporter adapted toclamp the carpct 88 firmly thereto by means of the thumb nuts 89.

90 is a forked or recessed guide that embraces the upper edge of thecarpet supporter and is shaped to conformto the various kinds ofstitching required. In Figs. 2, 4 and 12 the forked opening isrectangular. adapted for cross joint work where the inner edges of thecarpet are turned over upon the u )er ed e of the su) orter 72 far enouh to have the needle pass under the fourth warp 91 as represented byline 0 of Fig. 12. It is, however, immaterial what number of warps arein advance of the line of the needle provided there are enough to aiforda firm anchorage for the thread 'so that the onward strain against thesewed joint will not pull the warp from the woof.

For overcast work, the guide is actuated by the cam 92, Fig. 4, from themain shaft 29. This cam is embraced by the forked. lever 93 whoselower'end is pivoted on'the stationary rod 94 anchored in the machineframe. One end of the lever 95 is also pivoted on the rod '94 and itsopposite end carries the guide 90. In overcast work, the

two levers are connected together by the release pin, so that, whenthe'needle passes through the angular opening 97 of the guide,

at the point (Z, and under the fourthwarp of the carpet, as beforementioned, and has retreated, the guide will be depressed by the cam 92,so that the needle will pass through the opening in the guide at thepoint e and above the carpet. For other than overcast work, the releasepin 96 is removed, so that the lever 93 will simply oscillate on the rod94 under the influence of its actuating cam,

while the guide will remain stationary. When the guide is depressed, asbefore mentioned, it will depress the carpet supporter 72 and alsocompress the springs '86, so that the carpet support will alwaysmaintain its proper relative position with respect to the guide andcarpet.

For raw edge or miter work, the upper edge of the carpet supporter 90 isangular or beveled as shown in Fig. 5, and the bottom of the forkedguide is correspondingly shaped. Through and through sewing andovercasting can be done with the guide and supporter V-shaped as well asin the construction just described for Fig. 4.

For serging or converting a raw edge into a selvage edge, the guide 90shown at'Fig. 6 is employed, wherein the end of the carpet is bent overso that the path of the needle,

' represented by line 0, will pass between the plush and the warp andwoof of the carpet as shown. The line 0 represents the path of theneedle in Figs. 5, 6 and 12.

The machine feeding arrangement shown in Figs. 13 and 14 is adapted foruse with either hand operated or automatically operated machines. Inthis construction, the forked lever 98 is pivotally supported on the rod94 and is actuated by the cam 99 on the main shaft 29. 100 is aretractile spring that maintains the lever normally in contact with thecam, and the spring 101, wound about the lower forked ends of the lever,is anchored to said forked ends and the serrated faced feed fingers,101,102, journaled on screws 10&, so that said fingers are normallyengaged with the carpet to feed the machine along. Either of saidfingers are adapted to be temporarily disengaged from the carpet asshown by the open position of the fingers 103, 104.

One edge of the carpet supporter 72 can be shaped as shown in Figs. 2and 12, and the opposite edge shaped as shown in Fig. 5, so

that it will simply be reversed for the different manner of stitchingrequired.

Having thus described my invention, what I claim is:

1. In a carpet sewing machine, carrying a shuttle for making a lockstitch, and a looper for effecting a loop stitch, mechanism for changingfrom one form of stitching to the other, comprising a housing platesocurely mounted on the main shaft and havin g an inwardly projectinghub, a cam j ournaled on said hub for actuating the looper,a change pinoperatively mounted in the housing plate and adapted to engage the camand cause said cam to rotate with the shaft, and to remain idle when thechange pin is withdrawn and the shuttle is operating, and means forlocking said pin when either the shuttle or looper is in operation.

2. In a carpet sewing machine having supporting standards, mountedthereon, and a spring controlled carpet supporter mounted in saidbrackets.

3. In a carpet sewiiig machine of the character described, a carpetsupporter having removable brackets its edge shaped to conform to theseam to be stitched, supporting guides for the carpet supporter, springsunderlying said carpet supporter, a recessed guide carried by themachine having the bottom of said recess shaped to conform to the edgeofthe carpet supporter, and means for actuating the guide to temporarilydepress the carpet supporter during the operation of over casting.

In testimony'whereof I affix my signature in presence of tWo witnesses.
